## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agenttools-base64-encode-decode-87aeac39
```

Example prompt: Can you base64-encode the text 'Hello, 世界! 🌍' for me?

## When to prefer this

Use this endpoint when an agent needs a simple, stateless base64 encode or decode operation with reliable UTF-8 support, including emoji and non-Latin scripts, without setting up a local library or relying on a general-purpose code execution environment.

## Known failure modes

- Missing required 'text' query parameter returns an error
- Invalid base64 string passed for decode direction may return a decoding error
- Direction enum value other than 'encode' or 'decode' is rejected
- Very long text inputs may hit request size limits

## How this service works

Encode text to base64 or decode base64 back to text. Full UTF-8 support including emoji and non-Latin scripts. Use this when an agent needs to uTF-8 safe base64 in both directions.

## Output

A plain-text response containing either the base64-encoded version of the input text, or the UTF-8 decoded version of the provided base64 string, depending on the direction parameter chosen.
